HI @standalone
As @TMacD said you can change the
Page. There is a tutorial on Setting playback timings/durations which may help you.
You can also set chord duration in terms of the no of beats in the SETTINGS. Combinig these two settings will enable you to extend the chord duration signifcantly.
In order to play a single note place a chord in Section C and then delete notes from the chord on the CHORD pageThere are two tutorials that may help you: Introduction to the CHORDS page and The Chord Page: Entering Custom Chords.
Hope this helps
